Your Brother and His Girlfriend

That's not what you wanted to see. Your brother is starring into you, wide eyed with fear. Instinctively he uses his hands to cover his crotch, his girlfriend is covering her breasts and crosses her legs.

"H-hi." He says, playing dump. "Hey. What are you doing?" You have the power here.

"I'm just playing around." His eyes are really wide.

His girlfriend at this point has been looking for her clothes. She finds her bra but fumbles to clip it on. She turns her back to your brother. "Could you help me?" she asks. Your brother helps her.

"Please don't tell mom... or dad."

If your more traditional parents knew that your brother is having sex they'd be mad. Mad enough to really punish your brother, even if he's the older adult he still relies on your parents support.

His girlfriend looks at you. "Don't tell my parents either, they'd really would kick me out."
